I know next to nothing of hiking, so I’d be interested in hearing of your trips and tips and whatever else!
My limited knowledge roughly amounts to go with someone (genuinely) experienced, have more water (and probably food) than you’ll think you need, good footwear, be wary of the mystery berry, and don’t try to pet/touch all the wildlife (no matter how cute they may seem).
You need space between your toes and the toe of your boots. If you don’t have that space, your toes will turn into blisters.
Go to REI and have them fit you for boots and a pack. Yes, you can get gear cheaper on Amazon, but getting gear that fits you right is worth the extra cost.
Plan on 1L of water for evey hour on the trail. Drink it even if you don’t feel thirsty. Your pee should be nearly clear.
Buy trekking poles and learn to use them properly.
Leave your music at home, or wear headphones. No one wants to hear it.
The slowest person in your group leads.
Learn how to use a map and compass
Wear brightly colored clothing in case you get lost.
If you get lost, stay the fuck where you are. An emergency beacon is a must if you’re going deep in the back country alone.
This is all just for hiking. For backpacking I have way more.
